The number of cases involving one specific STD is at an all time high, but that may prove an intensive testing program is working.

The South Omaha Public Library offered free STD testing Wednesday afternoon and the testing is regularly offered at libraries around Omaha.

Douglas County Health Department representatives said more people came in for the tests in 2014 than in years prior.

"So it is working," Dr. Adi Pour, Health Department director, said. We see individuals who need to be tested and treated coming to the libraries."

The report indicated 1,500 people used that option, and health officials found 7 percent of them carrying an STD. Pour said 99 percent of those who found out they had an STD through this testing finished treatment.

However, the chlamydia rate reached an all time high in 2014: 3,390 reported cases -- a 5 percent increase from 2013.

Cases of gonorrhea are up by 15 percent and syphilis cases are up by 23 percent.

The biggest concern for many on the Douglas County Board of Health is that the rates continue to rise for one age group -- people 20-24 years old.

"At this point, we've got to go back and assess, because at age 20-24 you are an adult making solid decisions," Chris Rodgers said.

A new STD awareness program through the Women's Fund launches last month, targeting young people with reminders around the city.

"What we found was that they lack sufficient knowledge about STDs," Rodgers said. "They're engaging in risky sexual behavior."

Most in attendance at Wednesday's meeting agreed that the library testing sites are helping, but there's still work to do.

"It is frustrating," Pour said. "It's frustrating as a community."

Douglas County's STD rate remains above the national average. If you're interested in the free testing at local libraries, the Douglas County Health Department posts the testing times and sites on its Facebook page.
